Many people want to plant some small radishes on the balcony, especially for cherry radishes . These small radishes types (many varieties), they are more suitable for potted plant maintenance. If it is on the terrace, you can also choose red water radishes and other varieties. If it is planted in the yard, then any variety can be planted at will. Before
potted radish, you must also understand clearly that radish is more likely to provoke aphids and leaf fly (after all, it is a typical cruciferous plant ). Be sure to pay attention to preventing in advance. Some of my friends planted radishes that only grow leaves but not tubers. After encountering this situation, they harvest the radish leaves and eat them.
. Planting time (temperature)
Friends can choose the right time to plant radishes (mainly depends on the temperature). If it is in in South China, it is more suitable to start sowing in early October; if it is in Yangtze River basin, it is more suitable to sow in August and September; if it is in the north, it is more recommended to start sowing in June and July, or in February and March of the following year.
The timing of sowing is actually related to the growth period of the radish. Radishes do not like environments with too high temperatures. It is best to wait for the temperature to drop below 25 degrees sowing. The optimal growth temperature is between 5 and 25 degrees.
, container and soil
If you are planting small cherry radishes, you only need to use a flower pot 20-25 cm deep, and you can plant them. If you are growing red water radishes, it is recommended to use a container 25-30 cm deep. You can choose a long flower pot, a planting bag, or you can choose an assembled flower tank.
Before planting radishes, in addition to preparing a suitable container, you should also prepare sterile soil without insect eggs. It is best to sterilize the soil before planting. The potting soil should be loose and breathable, and has more fertility.
If you want to prevent pests in advance, you can spray some organic insecticides regularly, such as neem oil , azadirectin , etc., and you can spray it every ten days and half a month.
The harvest period of these small radish varieties is relatively short. For example, cherry radish can only be harvested for one month, while red water radish can be harvested for one and a half months.
Some flower lovers plant radishes that only grow leaves but not tubers. In fact, it means that the base fertilizer is insufficient (or insufficient light). Before planting, you can bury a relatively thick layer of rotten chicken manure, sheep manure or cake fertilizer at the bottom of the flower pot. After adding base fertilizer, cover the soil, and then water it thoroughly.
3. After watering and lighting
, you can evenly sprinkle radish seeds on the soil surface, cover a layer of soil one or two centimeters thick, and finally water it slowly once. Keep it in a ventilated and transparent place, and it is best to have proper light every day, and not in a shaded place. In the later stage, if the surface soil is dry, water it thoroughly. It usually takes two or three days to water it. It depends on the dryness and wetness of the pot soil.
As the radish seedlings continue to grow, the demand for light will increase. It is best to have direct light for more than 6 hours a day in the later stage.
4, interstitial seedlings
usually grow after 5 to 7 days. You can start to gradually increase the light. About two weeks, the seedlings will grow stronger. At this time, you can seedlings intermittently. Pick some of the weakly grown seedlings and overly dense seedlings, or cut them directly from the bottom of the rhizome, so that other strong seedlings can be damaged.
radish should not be too dense. After the first time the seedlings are intermittent, let them grow for a period of time, and wait until the seedlings have more than four real leaves, and then the seedlings are intermittent again. It is best to have a spacing of about five centimeters for each radish. They are small radish varieties. If you plant larger radish, it is recommended to have a spacing of 10 to 15 centimeters.
planted for about 20 to 25 days, and these small radishes began to grow small tubers (those that grow fast can be harvested).
5, Fertilization
If you are maintaining potted radishes on the terrace, you can regularly replenish these radishes. The most suitable organic fertilizers include wood ash , rice washing water, fruit enzyme , organic compost or organic manure, etc., which are also replenished every one or two weeks.
Banana peel or eggshell fertilizer introduced to you before can also be used, but the most suitable one is wood ash, which can be diluted 10 times with water and then used. If the plants of the radish grow relatively strong, you can sprinkle the wood ash directly on the soil surface. Not only can they be supplemented with potassium fertilizer , but they can also prevent bacteria and pests. Just sprinkle them evenly on the soil surface.
The vegetables you grow by yourself are best fertilized with organic fertilizer. Of course, you can also supplement them with phosphorus and potassium fertilizer .
